Abstract
เหล็กกล้าสำหรับทำสปริงที่มีคุณสมบัติที่ดีเลศในด้านความล้าภายใต้สภาวะที่มีการกัดกร่อน และไม่มีการกัดกร่อนและในความต้านทานการหย่อยตัวตามวงรอบซึ่งประกอบด้วยธาตุที่จำเพาะ เจาะจงดังต่อไปนี้ในหน่วย % โดยน้ำหนัก C 0.45-0.70% Si : 1.65-2.5% Mn : 2.20-0.75% Cr : 0.60-2% Ni : 0.15-1% Mo : เล็กน้อย -1% V : 0.003-0.8% Cu : 0.10-1% Ti : 0.020-0.20% Nb : เล็กน้อย -0.2% Al: : 0.002-0.050 % P : เล็กน้อย -0.015% S : เล็กน้อย -0.015% O : เล็กน้อย -0.0020 % N : 0.0020-0.0110% ซึ่งตามหลักแล้ว ตัวสร้างสมดุลจะเป็น Fe และสิ่งเจือปนที่ไม่อาจหลีกเลี่ยงได้ และโดยที่ปริมาณคาร์บอนสมมูล Ceq. ที่ถูกระบุด้วยสูตรต่อไปนี้ Ceq.=[C]+0.12 [Si]+0.17 [Mn]-0.1 [Ni] + 0.13 [Cr] - 0.24 [V] มีค่าตั้งแต่ 0.80 ถึง 1.00 % โดยที่ [C], [Si], [Mn], [Ni], [Cr] และ [V] แสดงปริมาณธาตุเหล่านี้แต่ละชนิดในหน่วย เปอร์เซ็นต์โดยน้ำหนักและโดยที่ความแข็ง Rockwell HRC ของเหล็กกล้าสำหรับทำปสริงมีค่าตั้งแต่ 55 ขึ้นไปภายหลังการชุบแข็งและการทำเทมเปอร์: Spring-making steel that offers excellent fatigue resistance under corrosive conditions. And non-corrosive and in resistance to cyclic degradation consisting of specific elements Specify the following in% by weight C 0.45-0.70% Si: 1.65-2.5% Mn: 2.20-0.75% Cr: 0.60-2% Ni: 0.15-1% Mo: nominal -1% V: 0.003-0.8. % Cu: 0.10-1% Ti: 0.020-0.20% Nb: Minor -0.2% Al:: 0.002-0.050% P: Minor -0.015% S: Minor -0.015% O: Minor -0.0020% N: 0.0020-0.0110%. In principle The balancer is Fe and its impurities are inevitable. And where the Ceq. Equivalent carbon content is indicated by the following formula Ceq. = [C] +0.12 [Si] +0.17 [Mn] -0.1 [Ni] + 0.13 [Cr] - 0.24 [V] ranges from 0.80 to 1.00% where [C], [Si], [Mn. ], [Ni], [Cr] and [V] represent the amount of each of these elements in units. Percentage by weight and where the Rockwell hardness HRC of the annealing steel is 55 or more after hardening and tempering:
